This is an unusual and increasingly hard to find Silver Oxide battery. It is commonly used in remote alarm controls for VW and Audi alarm systems and is particularly widely used in later Volkswagen Logic immobilisers known as Logic, Conlog or Conlogic. These immobilisers were widely fitted to Audi, VW and Land Rover vehicles.

Make Your Own:
You can easily make one of these from a stack of four SR41 button cells held with heat-shrink tubing or wrap some electricians tape around them. You may require some sort of "pip" for the end, depending on fitment. Be sure to use the Silver Oxide cells though as the Alkaline ones are not suited to this application due to the slightly lower voltage.
